Blast Demolition of Reinforced Concrete Industrial Chimneys

Document Type: Proceeding Paper

Part of: Spatial, Lattice and Tension Structures


On some of recently demolished chimneys, transient measurements were taken, in the vicinity of the tilting hinge, during the process of falling down. Thus, corresponding dynamic computational models could be verified and adapted. Computational result variations due to input variations are studied. The analytical models, on the combined basis consisting of three different branches: 1. full scale in-situ tests, 2. smaller scale laboratory detail tests, 3. computational models verified on both, are a well proved tool for solving practical problems and for explaining the occurring phenomena. The investigations are aiming at an artificial intelligence system, in future to be used as expert system for preparing chimney blast demolition based on the available knowledge in this field and using computer simulations.
